I have been trying to reply to this post for an hour.
I am currently experiencing the same problem. The launcher can barely load it's news feed and logging in is impossible, if the launcher loads anything but it's background at all.
Many of the sites associated are also having trouble, including this forum. Slow loads or no connection at all.

I assume this is a temporary thing, but it would be appreciated if these kinds of problems could be communicated through something like the FF14 twitter to keep people posted.
